(We're running SunOS 4.0 on a Sun 3/280.)

Description:
	Gnu gcc 1.33 and SunOS 4.0 make's .KEEP_STATE feature don't mix.
	The problem turns out to be in the preprocessor, which correctly
	detects that Sun's make wants dependencies written out but then
	writes only the dependencies (and not the results of preprocessing).
